WebService WSDL file parsing and sending and receiving of SOAP messages (no Java client code generated)

attached with page JSP, JS, and Dwr action,service and Util, my environment is spring, DWR, ext, jquery. Because the entire tool involved more, so did not complete the operation of the Code to organize, only the core of the code posted out, if you need to run to solve the small problems

In recent time, the company's QA testers need to provide a WebService testing tool, specific requirements for: Testers to provide WebService URL, test tools based on the URL to get WebService published methods and methods of parameters, and then testers in the page input parameters and click Run, and after the tool is run, the results returned on the page are displayed. In fact, testers can use off-the-shelf in the test framework Soapui to test webservice, but testers still feel trouble, team leader also require the tool can not use Wsdl2java to generate WebService client code. I think it may be that you don't want to store too many useless temporary files in your project.

the types of parameters and return values that the test tool supports are: arrays, lists, Java basic data types, Java objects, and nesting of these types. Tool screenshot below







here's how to implement the tool:
Parsing the method contained in the WSDL file using the WSDL4J tool based on the WebService URL parse the schema part of the WSDL using the DOM, and manually parse the parameters of the method using Soapui get the template that sends the SOAP request message to fill in the Sent SOAP request message Gets the return value in the SOAP message returned by the returned SOAP message resolution, which is displayed to the page

before you look at the implementation code, friends who do not understand WSDL and schema can familiarize themselves with the structure of the WSDL and schema files and the individual property fields based on the following URLs
WSDL: http://www.w3school.com.cn/wsdl/index.asp Schema: http://www.w3school.com.cn/schema/index.asp
